Map of USGS gauge 06335500 and the river around it
Where LITTLE MISSOURI RIVER AT MARMARTH, ND sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. North Dakota Game and Fish Department publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a North Dakota rule: 68°F.
Species list not on file for this gauge. Check the North Dakota Game and Fish Department: North Dakota fishing regulations.
Normal for Nov 5: 18–48 ft³/s (middle half of 88 years of record). Now: 39.6 ft³/s, normal.
Normal for this date. 39.6 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 88 years of record (1939–2026): 10th 9.1, 25th 18, median 25, 75th 48, 90th 110 ft³/s.
Daily means on record for Nov 5: lowest 0.5 ft³/s, highest 514 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Falling over 24 hours: discharge down 13.9%, from 46 to 39.6 ft³/s. Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.

Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 1 ft stage, 14 ft³/s at Nov 5, 7:00 PM CST (NWS gauge MTHN8; its stage datum can differ from the USGS gauge height).
